中文摘要: |
新疆伊吾县黑园山北部地区具有良好的控矿因素和成矿条件,但自然条件恶劣,常规野外地质调查工作量大,遥感技术为找矿工作提供了新思路。全文以SPOT 6、Landsat 8卫星数据为主要数据源,在该区进行遥感示矿信息提取与找矿预测应用研究。基于地质背景、矿床特征、矿床成因、遥感影像等资料,对多源卫星影像进行遥感构造、岩性解译,近矿围岩蚀变信息提取、蚀变程度分级设色,总结归纳研究区成矿地质特征,以羟基、铁染矿物异常等示矿信息为基础,对遥感找矿信息进行综合研判,通过建立地质-遥感综合找矿模型圈定了5个成矿远景区(找矿有利区域)。经高分辨率影像核查验证,其中3个成矿远景区发现线性勘探槽、采矿区等地面矿产勘查的痕迹,说明圈定区域对找矿工作有明显指示意义。 |

There are good ore-controlling factors and metallogenic conditions in the north of Heiyuan Mountain, Yiwu County, Xinjiang. However, the workload of routine field geological investigation is heavy due to the harsh natural environment. Therefore, remote sensing technology provides new ideas for ore-prospecting. Our application research focus on remote sensing mine-indicating information extraction and metallogenic prediction, with SPOT 6 and Landsat 8 satellite data as the primary data sources. Based on geological background, deposit characteristics, deposit genesis, remote-sensing images, and other data, remote sensing tectonic and lithologic interpretation of multi-source satellite images is carried out. The degree of wall rock alteration is graded and colored. The metallogenic geological characteristics of the study area is summarized based on the hydroxylate and ferric contamination anomaly information. The remote sensing prospecting information is studied and judged. By establishing the comprehensive prospecting model of geology-remote sensing with five metallogenic prospecting areas (favorable areas for prospecting) are delineated. Traces of surface mineral exploration such as linear trenches and mining areas are found in three metallogenic prospect areas through the verification of high-resolution images, indicating that the delineated areas have obvious indicative significance for ore- prospecting work. |
